Growing fish and plants using aquaponic, hydroponic and mixed technologies

Abstract

Aquapon technology has a positive effect on the growth of live weight of Clary catfish per 1m3 of the water environment in comparison with ultrasound. As a result, this indicator in the aquapon installation was higher by 456 grams or 1.1% for 45 days ompared to the USV. Profitability cleavage catfish in aquaponic operation installation was 22.8%, which is 1.4% higher than the same indicator of RAS. The combined aquaponic-hydroponic mode of operation of the unit allowed to obtain 8.282 kg of vegetative mass of lettuce plants from 1 m2 of the installation area for 45 days, which is 2.761 kg more than in the traditional aquaponic mode and 0.903 kg more than in the hydroponic mode.
